How to Find and Fix Hot and Cold Spots

If you find that you have hot and cold spots in your Genoa home, you’re not alone. This is a fairly normal issue. While it might seem like a major concern, the good news is that the common causes of hot and cold spots are usually easy to fix with a normal air conditioning service. The most likely causes for hot and cold spots are:

  • Zero zoning or improper zoning
  • Poorly designed or ineffectively sized duct systems
  • Leaky or inefficiently insulated air ducts
  • HVAC equipment that is too big or too small

Lack of Zoning or Improper Zoning
A zoning system breaks up your home into separate areas, known as “zones,” and means you’re able to determine the air temperature in each zone. The system is composed of multiple thermostats that control dampers within the ductwork of your forced-air system. The thermostats are working nonstop, reading the temperature of their designated zone, then open or close the dampers to meet the thermostat's settings. This could be the missing piece to keeping that one frozen bedroom warm in the winter, or that smoldering sunroom comfortable all summer. Plus, when it’s used with a programmable thermostat, zoning could mean home energy savings of up to 35 percent.*

Poorly Designed or Ineffectively Sized Duct Systems
Some homeowners have hot and cold spots simply because their home’s duct system is not sized appropriately for the area that needs heated and cooled, or it’s improperly designed. We find this is fairly common in homes that were built before a lot of today’s tools and training were available. Unfortunately, even the most energy-efficient HVAC equipment can’t meet homeowners’ expectations if the duct system isn’t permitting it to do its job. In fact, a poor duct system could actually cause new equipment to work more often than needed and decrease its life cycle. The pros at Assured Appliance and Heating & Air can help you figure out if your duct work is working for your home.

Leaky or Inadequately Insulated Air Ducts
Even if your duct system is designed and sized properly for your home, it might still be the source of your home’s hot and cold spots. It’s common for the ducts in a home to leak a bit over time. Professionals like Assured Appliance and Heating & Air can check your ducts and let you know if they ought to be sealed. They may also find that your ducts aren’t leaking, but they’re not correctly insulated. Fortunately, this is also a generally easy fix.

Improperly Sized HVAC Equipment
So possibly your air duct system is just fine and you have a good zoning system, but you’re still experiencing hot and cold spots throughout your home. Improperly sized HVAC equipment might be the culprit. A system that is too small has to run harder to heat or cool your home, leaving you with hot and cold spots because it can’t keep up with the amount of space it needs to condition. Even a system that’s too big can cause problems because it’ll cycle on and off too often to do its job properly.
